old screen door cabinet - would make a great pantry! Would also look good with a wood door cut in half for 2 doors. I'd say make this and attach it to outside of the house for an outdoor garden tool closet!
Could this work for the mudroom bench? Use an old door for a bench. Can totally see this near the backdoor with some type of shelf above it with hangers to hang coats and put shoes or other baskets to hold items under the bench.
From old door to beautiful catchall. Add some shelves or wire baskets as this one shows. I love the addition of the mirror! You can find directions for how to build something similar from This Old House New Takes On Old Doors: Salvaged Doors Repurposed
